[$] Comparing BPF performance between implementations

Alan Jowett returned for a second remote presentation at the 2024
Linux Storage,
Filesystem, Memory Management, and BPF Summit to compare the performance of
different BPF runtimes. He showed the results of the MIT-licensed BPF

microbenchmark suite he has been working on.
The benchmark suite does not yet provide a good direct comparison between all
platforms, so the results should be
taken with a grain of salt. They do
seem to indicate that there is some significant variation between
implementations, especially for different types of BPF maps.
